前言介绍
对于本考研信息查询系统的设计来说，它主要是采用java技术。在整个系统的设计当中它是应用mysql数据库来完成的，具体根据网上考研资讯平台的现状来进行开发的，具体根据学生需求实现网上考研资讯平台网络化的管理，各类信息有序地进行存储，进入考研信息查询系统页面之后，方可开始操作主控界面，系统功能包括学生前台：首页、导师信息、学校介绍、专业信息、项目信息、论坛、个人中心、后台管理、登陆、在线客服，管理员：首页、个人中心、考研资讯管理、学校介绍管理、导师信息管理、考生信息管理、专业信息管理、设施申请管理、项目信息管理、论坛管理，系统管理。导师后台:前页，个人中心，设施申请管理。考生后台：首页、个人中心、设施申请管理
